Product details
Overview
5962-9469101Q3A from Texas Instruments is a military-grade 10-bit D-type bus-interface flip-flop with 3-state outputs, designed for high-reliability data latching and bus driving in aerospace and defense systems. It operates across –55°C to 125°C, delivers ±32-mA high-drive outputs (IOH/IOL), features low ground bounce (<1 V VOLP), and maintains high-impedance state during power-up/down at VCC < 2.1 V.
For engineers reviewing the 5962-9469101Q3A datasheet, 5962-9469101Q3A pinout, 5962-9469101Q3A application, or 5962-9469101Q3A equivalent, this page provides verified functional identity, military-temperature timing specs (125 MHz max clock), EPIC-IIIB BiCMOS power efficiency, latch-up immunity (>500 mA), and ceramic LCCC package details - all critical for avionics I/O buffer qualification and radiation-tolerant system design.
Technical Context
This device implements ten edge-triggered D-type flip-flops synchronized to the rising edge of CLK, with independent asynchronous 3-state control via OE. Its BiCMOS architecture enables TTL-compatible input thresholds (VIH = 2 V, VIL = 0.8 V) while supporting 4.5–5.5 V supply operation and delivering rail-to-rail output swing under heavy capacitive loads.
Internal power-up sequencing ensures automatic high-impedance output state when VCC is between 0 and 2.1 V; above that threshold, OE must be pulled to VCC to guarantee tri-state behavior. The device retains stored data during OE assertion and supports hot-insertion due to high-impedance isolation and ESD protection exceeding 2000 V per MIL-STD-883 Method 3015.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit bus-interface flip-flop applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 5962-9469101QLA | Ceramic DIP (JT), 24-pin, same electrical specs and temp range | Through-hole mounting; larger footprint; lower frequency margin due to higher package inductance | Select for legacy board repair or manual prototyping where LCCC rework is impractical |
| SNJ54ABT821W | Ceramic flatpack (W), 24-pin, identical logic but different mechanical form factor and lead finish (A42) | Surface-mount alternative with gull-wing leads; not hermetically sealable like FK | Choose when board assembly uses standard reflow profiles and hermeticity is not required |
Compared with 5962-9469101Q3A, the 5962-9469101QLA offers through-hole reliability at the cost of higher parasitic inductance, while SNJ54ABT821W provides surface-mount compatibility without the LCCC's hermetic sealing - making 5962-9469101Q3A the only option for sealed, high-vibration, space-qualified deployments requiring zero moisture ingress.

FAQ
What is the maximum clock frequency supported by the 5962-9469101Q3A?
The 5962-9469101Q3A supports a maximum clock frequency of 125 MHz across its full operating temperature range (–55°C to 125°C), as specified in the SCBS193E datasheet under timing requirements. This value is validated at VCC = 5 V and TA = 25°C, with guaranteed minimum pulse widths of 2.9 ns (high) and 3.8 ns (low) for reliable edge triggering. The 5962-9469101Q3A achieves this performance using EPIC-IIIB BiCMOS technology to balance speed and power efficiency.
Does the 5962-9469101Q3A require external pull-up resistors on the OE pin?
Yes - to ensure guaranteed high-impedance output state when VCC exceeds 2.1 V, the OE pin of the 5962-9469101Q3A must be tied to VCC through an external pullup resistor. The minimum resistor value depends on the current-sinking capability of the driver controlling OE; TI recommends verifying drive strength against the 10-µA IOZH/IOZL specification. The 5962-9469101Q3A enters high-Z automatically only when VCC is between 0 and 2.1 V.
What package type is used for the 5962-9469101Q3A and what are its key mechanical attributes?
The 5962-9469101Q3A uses a 28-pin ceramic leadless chip carrier (LCCC) package designated FK. It measures 1.240 × 1.280 inches (31.5 × 32.5 mm), features a J-lead configuration, and is hermetically sealable per MIL-STD-1835 GDIP3-T24. Pin 1 is marked by an index point on the ceramic cap, and four pins (12, 13, 25, 26) are no-connect. The 5962-9469101Q3A's FK package supports high-reliability applications requiring zero moisture ingress and mechanical stability under shock/vibration.
How does the 5962-9469101Q3A handle power-up sequencing in multi-rail systems?
The 5962-9469101Q3A automatically places all ten outputs in high-impedance state when VCC is between 0 and 2.1 V, preventing bus contention during power ramp-up or brownout. Once VCC exceeds 2.1 V, OE must be actively driven high (or pulled up) to maintain high-Z. This behavior is intrinsic to the BiCMOS input structure and does not require external reset circuitry - a key advantage for fault-tolerant 5962-9469101Q3A deployments in avionics and defense systems.
Is the 5962-9469101Q3A compliant with MIL-PRF-38535, and if so, which quality levels?
Yes - the 5962-9469101Q3A is manufactured and tested to MIL-PRF-38535 requirements, specifically qualified as a Class V (space) and Class Q (high-reliability) device. It undergoes screening including burn-in, temperature cycling, and radiation hardness assurance testing per the specification. The 5962-9469101Q3A part marking "5962-9469101Q3A" and manufacturer ID "SNJ54ABT821FK" confirm its compliance, and it is listed in TI's Qualified Manufacturers List (QML) for military-grade logic.
